7 Application filed. December 23, 1913. Serial No. 808,346.

To all whom it may concern Be it known that I, HENRY TURNER, a subject of the King of Great Britain, residing at Richmond, in the'county of Henrico and State of Virginia, have invented certain new and useful Improvements in Pads for Packing Tobacco and Processes for Making the Same; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to the mode of manufacturing pads for packing tobacco and one of the principal objects of the same is to lessen the time of operation and save expense and in the provision of simple and efficient means for giving the end plugs in a caddy of tobacco the desired appearance to render such end plugs salable.

Heretofore it has been proposed to place large particles of tobacco or tobacco leaves in the ends of the caddy prior to submitting the tobacco to hydraulic pressure; but this process is comparatively slow and when the caddy of tobacco is received by the retailer the particles of tobacco must be removed from the ends of the caddy before the plugs are removed for sale.

The method contemplated by this invention comprises a matrix or pad made up of a piece of card board having tobacco leaves connected thereto and said matrices being placed at the opposite ends of the caddy before the pressure is applied so that the end plugs will have the appearance of the plugs in the center of the caddy, that is to say the outer surfaces of the end plugs will have the rough and undulated surface of the inner plug, instead of being smooth and flat, owing to the pressure of the end of the caddy upon the ends of the tobacco plugs.

By making up these pads and having them ready to use, considerable time is saved in the packing of the tobacco, and there are other advantages incidental to this process which will appear hereinafter.

In the accompanying drawing, Figure l is a plan view of a pad or matrix in an unfinished condition, Fig. 2 is a face view of the pad or matrix in finished condition, Fig. 3 is a pad or matrix treated in a different manner and producing a slightly different effect upon the plug of tobacco, and Fig. 4 is a sectional view of a caddy for containing plugs of tobacco after the same have been packed therein, said caddy being shown in section, and two of the pads or mztcpices being disposed at'the ends of the ca y.

In carrying out this invention a piece of card board or layer of paper stock board a is utilized. This card board is preferably first treated with parafiin, and upon one side of the card board or paper board a coating of some adhesive material is applied, preferably a compound made up of gum arabic and glucose. To the card board a is con nected a number of pieces of tobacco leaves I), the adhesive surface of the card being moistened to connect these pieces of tobacco thereto. As shown in Fig. 1 the tobacco leaves or pieces Z) do not cover the entire surface of the card board a but leave certain spaces 0 uncovered by the tobacco.

g The next step in the method of preparing the pads or matrices consists in taking a leaf of tobacco, or a number of leaves or pieces cl, by means of which the entire surface of the card board a is covered and the leaves cZ also extending over the pieces 0 as shown in Fig. 1, said leaf being connected to the adhesive compound in the spaces c 3.113 thereby held in place on the matrix or pa As shown in Fig. 3 the card board blank s also treated with paraflin and has one of 1ts surfaces coated with an adhesive compound, and connected to the adhesive side of the blank a are numbers of pieces of tobacco e which entirely cover the surface of the card, this being a modified form of the matrix which serves substantially the same purpose as the one already described.

The manner of using the pads or matrices may be briefly described as follows :The hydraulic press has one of the matrices or pads placed in the bottom thereof before the plugs f are packed therein. The matrix which is indicated by the letter a is like the pad shown in Fig. :2, and the tobacco leaf 6 is uppermost so as to form an impression in the end plugs in the press. After the tobacco plugs have been packed in the press another matrix or pad, indicated at a is placed upon the upper layer of plugs with the tobacco leaf adjacent to the upper surface of the plugs. In this condition the caddy is placed in a press and pressure is applied to the caddy. The cover is then secured to the caddy and the package is ready for shipping or storing.

From the foregoing it will be obvionsthat the plugs of tobacco at the top and bottom of the caddy receive the impression of the leaf 1) or the pieces of tobacco 0, thus obviating the plain, smooth end plugs in the caddy which are unsalable owing to their smooth appearance and condition.

It will be understood that the matrices or pads may be made the exact size of the plugs if so desired instead of extending across two or more plugs, as shown.

Certain modifications in the details may be resorted to without departing from the spirit and scope of the invention as defined by the claims.

What is claimed is e 1. A process of securing tobacco to cards to form matrices and pads for giving impression to the end plugs in a caddy which consists in coating a piece of card board with parafiin, applying an adhesive compound composed of gum arabic and glucose to one side of said card, attaching pieces of tobacco leaf to said adhesive side of the card board and finally covering the entire adhesive side with tobacco leaves and drying the same.

2. A pad or matrix to be used for the purpose referred to, comprising a flat paper board having its entire surface coated with parai'fin, and having one of its sides covered with an adhesive compound to which is attached acovering of'tobacco leaves to give impressionsto the end plugs ina caddy containing tobacco.

In testimony whereofI aiiix my signature V in presence of two witnesses.

HENRY TURNER.
